Therefore, each of the fixing part and the mounting part can be adjusted so as to approach the existing construction member positioned between them, or between the existing construction members and the utility pole, and the extension direction of the brace Even when the electric wire to be installed and supported can be shaken by reducing the displacement to the position, the newly connected installation member can be positioned on the arm metal with high reliability.

  As described above, according to the present invention, the connecting portion of the installation member can be connected to the connected portion of the mounting portion attached to the arm metal without requiring a through hole or the like that is vacant in the arm metal, For example, even if the connected part of an existing armor is damaged due to a fallen tree or the like, the erected member can be attached to the armor at an early stage without replacing the armor without replacing it. Can be connected. Therefore, the electric wire can be installed and supported on the added healthy construction member without exchanging the brace connected to the damaged construction member, and the power transmission is resumed quickly to complete the restoration work in a short time. be able to.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described with reference to the drawings. 1-7 is a figure which shows one Embodiment of the fixture of the electric wire construction member based on this invention.

  In FIG. 1, the wire erection member fixture 10 can connect the erection member of the pin insulator 120 and the retaining insulator 130 described with reference to FIGS. The main body member (attachment portion) 11 to be attached to the arm metal 110 and the auxiliary member (fixation portion) 12 to be fixed to the arm metal 110 at a location separated from the main body portion 11 are provided. Includes an adjustment plate (continuous portion) 13 that enables the auxiliary member 12 to be continuously provided and adjusts a separation interval thereof, and a connecting pipe (connected portion) 14 that connects the pin insulator 120 and the retaining insulator 130. It is fixed.

  As shown in FIG. 2, the main body member 11 and the auxiliary member 12 are each formed so that the vertical cross-sectional shape is a U-shape, and the top plate portions 11 a and 12 a are the inner surfaces of the upper surface of the arm metal 110. The side walls 11b and 12b are formed to have a width and are longer than the height of the side surface of the arm metal 110, so that the side walls 11b and 12b can be covered in a state of projecting downward. It is made so that it can.

  The main body member 11 and the auxiliary member 12 are screw holes 11c, 12c so that a general-purpose tightening bolt 15 can be inserted in the vicinity of the side wall portions 11b, 12b projecting downward from the side surface when the arm member 110 is covered. Is open.

  The adjustment plate 13 is horizontally fixed to one end side of the main body member 11 so as to protrude outward at a height substantially equal to the screw hole 11c, and the adjustment plate 13 has the screw hole 11c. Screw holes 13c that are equivalent to those are opened so as to continue to a plurality of locations in the extending direction.

  As a result, the body member 11 and the auxiliary member 12 are respectively inserted into the screw holes 11c and 12c of the side wall portions 11b and 12b which are placed on the arm metal 110 and project downward from the side surfaces thereof, and nuts (not shown) are inserted. By screwing and screwing, the arm metal 110 can be fastened and fixed without requiring a through hole (connected portion) or the like, and the adjustment plate 13 of the main body member 11 can be fixed. The main body member 11 and the auxiliary member 12 are connected and fixed at an arbitrary interval by aligning any one of the screw holes 13c with the screw hole 12c of the auxiliary member 12 and inserting the tightening bolts 15 and fixing them. Can do.

  The connecting pipe 14 is a through-bolt 137 (FIG. 7) for screwing a bolt portion 122 projecting from the lower portion of the pin insulator 120 shown in FIG. 3 and a retaining metal 136 connected to the tip of the anchor insulator 130 shown in FIG. The connecting tube 14 is formed in a tubular shape having a connecting hole 14a into which the connecting portion 14 can be inserted. The connecting tube 14 is parallel to the extending direction (vertical direction) of the side wall portion 11b of the main body member 11. So that it is fixed.

  Thereby, when the main body member 11 is attached and fixed to the arm metal 110, the connection tube 14 is attached to the arm metal 110 in a posture extending in the vertical direction, and is equivalent to the through hole of the arm metal 110. The holes 14a can be prepared on both side surfaces of the arm metal 110, and the bolt holes 122 of the pin lever 120 and the through bolts 137 of the retaining lever 130 can be inserted into and connected to the connecting holes 14a. Here, as shown in FIG. 4, the retaining lever 130 is connected to a retaining metal 136 for inserting the pin member 133 into the opening 131 a of the head 131 and screwing it to the arm metal 110, and the protruding pin 132 at the rear end. The head 131 of the other retaining lever 130 is connected and fixed to the opening 132a, and the electric wire D connected to the jumper wire d is connected and fixed.

  Therefore, in the fixture 10, as shown in FIG. 5, for example, even if the pin insulator 120 ′ damaged by a fallen tree or the like cannot be removed and remains (connected) in the armor 110, By selecting the screw hole 13c of the adjustment plate 13 and adjusting the interval, the main body member 11 and the auxiliary member 12 can be attached and fixed so as to be positioned on both sides of the pin insulator 120 ′. The bolt part 122 of the healthy pin insulator 120 which is not damaged can be inserted into the connecting pipe 14 and fixed by screws to be attached. In this fixture 10, the main body member 11 and the auxiliary member 12 can be attached to the bolt portion 122 of the damaged pin insulator 120 ′, so that the bolt portion can be displaced even in the direction in which the arm metal 110 extends. It is possible to limit the position by making it stop at 122, and it is possible to prevent it from coming off from the brace 110.

  Moreover, in this fixture 10, when the damaged pin insulator 120 'cannot be positioned between the main body member 11 and the auxiliary member 12, the screw hole 13c of the adjustment plate 13 is selected and the interval is adjusted. For example, the main body member 11 and the auxiliary member 12 can be attached and fixed so as to be positioned between members such as the electric pole 100 and its pin insulator 120 ', and the connection pipe 14 of the main body member 11 is not damaged. The bolt part 122 of the pin insulator 120 can be inserted, screwed, connected and fixed. In this fixture 10, the main body member 11 and the auxiliary member 12 approach the bolt portion 122 and the utility pole 100 of the damaged pin insulator 120 ′, and can be attached in a so-called stretched state. Even if it is about to deviate in the direction, it can be restricted by making contact with the bolt part 122 or the utility pole 100, and it can be prevented from coming off from the arm bracket 110.

  As a result, as shown in FIG. 6, even when the pin lever 120 of the arm metal 110 is damaged, the pin insulator 120 can be newly connected by mounting and fixing the fixture 10 to the arm metal 110. The distribution line D can be fixed and installed on the insulator 120 so as not to swing.

  Furthermore, as shown in FIG. 7, in the fixture 10, similarly, in the case of the retaining lever 130, for example, the retaining bracket 136 ′ damaged by a fallen tree or the like cannot be removed and remains on the arm metal 110 (connection). In this state, by selecting the screw hole 13c of the adjustment plate 13 and adjusting the interval, the main body is prevented from being displaced in the extending direction of the arm metal 110 or coming off the arm metal 110. The member 11 and the auxiliary member 12 can be attached and fixed, and a through bolt 137 is inserted into the connecting pipe 14 of the main body member 11 so that the undamaged healthy retaining metal 136 is screwed and the retaining insulator 130 is attached. it can.

  As a result, even if the retaining lever 130 and the retaining bracket 136 of the arm metal 110 are damaged, the anchor 10 can be attached and fixed to the arm metal 110 to newly connect the retaining insulator 130 and the retaining metal 136. The distribution line D can be fixed to the retaining insulator 130 so as not to swing.

  As described above, in this embodiment, the pin insulator 120 ′ and the like that are damaged and cannot be reused remain without being removed from the arm metal 110, and the pin insulator 120 is newly connected to the arm metal 110. Even when there is no through hole to be opened, the fitting 10 can be attached to the arm bracket without performing a new drilling operation and without deteriorating the strength by drilling the new through hole. The pin insulator 120 and the like can be separately connected and fixed simply by being attached to 110. Therefore, the pin insulator 120 or the like can be quickly attached to the arm metal 110 without replacing the arm metal 110, and the distribution line D can be installed and supported, and power transmission can be resumed early to complete the restoration work quickly. be able to.
